New chair from legendary designer Niels Diffrient

Humanscale's new Diffrient World Chair is the latest outing from legendary designer Niels Diffrient, the man who (as Bruce Sterling points out) literally wrote the book on ergonomics. Reading this description is sheer chairporn. $740 is out of my budget, though I have no doubt that it's worth every penny.
Made from just eight major parts and weighing less than 25 pounds, the Diffrient World chair achieves Humanscale's signature weight-sensitive recline through an innovative new design that functions without a mechanism. Utilizing two frame components, the user's body weight, and the laws of physics, the Diffrient World chair's mech-free recline action automatically adjusts to the needs of each user, offering appropriate levels of resistance without unnecessary locks, dials or other manual controls.

Like its older sibling, the award-winning Liberty chair, the Diffrient World chair features Form-Sensing Mesh Technology that ensures perfect lumbar support for every user without the external, manually adjusted lumbar devices found on all other mesh chairs. Additionally, a mesh seat pan with a frameless front edge provides all-day comfort with soft support under the thighs.
